Guide: How to Buy an Avalanche Beacon

The greater a beacon's range, the more likely it is to be able to receive a signal early in the search process.

Two or three antenna beacons have quickly become the norm due to their improved distance and directional sensitivity; the three-antenna design is a further improvement that helps to reduce signal spikes when doing close, precise searches.

Some advanced beacons enable you to mark multiple burial victims, and can automatically guide you to the closest signal (blocking out all others) to drastically reduce search time in the event of a multiple burial.
